 The differences between Bryophyllum and Kalanchoe seem purely technical.

Calyx 5- rarely 6-partite, equalling* or shorter than the corolla-tube. 

 Corolla-tube narrow or wide, urceolate or cylindrical, terete or 5- 

 gonous, limb 5-6-fid, segments usually spreading'. Stamens 10-12, 

 inserted on the corolla-tube, filaments filiform, short or elongated ; 

 anthers oblong, exserted or included. Squamulae linear, oblong" or 

 square, sometimes broader than long. Carpels 5-6, free, attenuated into 

 filiform or subulate often exserted styles, with obliquely capitellate 

 stigmas ; ovules many. Follicles many-seeded. — Herbaceous or shrubby, 

 branched or scapigerous, varying much in habit. Leaves opposite or 

 alternate, sessile or petiolate, often very thick and fleshy, rarely peltate, 

 sparse or rosulate. Flowers erect or pendulous, varying in size, race- 

 mose or cymose, often showy. Corolla-lobes twisted in aestivation. 



A genus of about 70 species, occurring in West and South Europe, throughout 

 Africa especially at the Cape, in Eastern Asia, the Himalayas, and Mexico. 



Flowers 5-merous.

Also in Britain, Western Europe, the Canary Isles, and N. W. Africa. In Tropical 

 African specimens the pedicels are shorter and the flowers more globulous than in 

 European examples.
